Redash has a spinner (zmdi-spinner / fa-spinner).
I’d like to discuss alternatives with more visual appeal.

Worked on a demo of a loading indicator using the Redash logo.

Feel free to fork it and suggest your own version

Amazing 
Let’s add it index.html so it appears while people are waiting for our static assets to load.
. Looking forward to see it on Redash
